Features:

  • Supports Dual-Channel Tachometer Signal Monitoring With High Accuracy
  • Provides External Terminations For Flexible Field Wiring
  • Delivers Buffered Outputs For Seamless Integration With 3500 Rack Monitors
The Bently Nevada 133434-01 I/O Module with external terminations is engineered for precise dual-channel input in the 3500/50M tachometer system. It accepts signals from proximity probes or magnetic pickups to monitor shaft speed, rotor acceleration, and rotor direction. Compared with the 133442-01 internal termination version, 133434-01 uses dedicated external cables for connection, offering more flexibility in field wiring and simplifying installation in complex industrial layouts.

Equipped with buffered outputs via Euro-style connectors, the 133434-01 can supply conditioned signals to other 3500 rack modules, eliminating the need for additional Keyphasor hardware. The module consumes 5.8 Watts, operates in temperatures from -30°C to +65°C (-22°F to +150°F), and mounts in a single full-height rear slot on the 3500 frame. This design ensures reliable signal acquisition while maintaining flexibility for maintenance and reconfiguration.

When used in conjunction with the 3500/50M Tachometer Module, 133434-01 supports advanced monitoring features including speed alarms, speed band alarms, zero-speed notification, rotor acceleration alarms, and reverse rotation alerts. Its dual-channel capability combined with external terminations allows operators to optimize sensor placement and wiring management, providing a robust, high-fidelity solution for critical rotating machinery monitoring.

The 133434-01 Bently Nevada I/O Module with External Terminations may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Temperature Range: Operating temperature: -30°C to +65°C (-22°F to +149°F). Storage temperature: -40°C to +85°C (-40°F to +185°F). Humidity: Up to 95% relative humidity, non-condensing.
  • Physical Protection: As part of the 3500 frame, typically installed in an instrument panel cabinet conforming to IP54 or higher standards.
  • Hazardous Area Certifications: North America: Class I, Division 2, Groups A, B, C, D. International (ATEX/IECEx): Applicable to Zone 2 hazardous areas (Ex nA nC ic IIC T4 Gc).
  • High-Density Cabinet Installation: When space behind the 3500 frame is limited and direct wiring is not possible, wiring can be routed to the rail via external terminal blocks (ETBs) for easy installation.
  • Rapid Maintenance Requirements: I/O modules can be quickly swapped out without disconnecting field sensor wiring, significantly reducing maintenance downtime.
  • Large Rotating Machinery Protection: Widely used in steam turbines, gas turbines, multi-stage compressors, and large pump sets for overspeed protection and zero-speed monitoring.
  • Remote Wiring Requirements: External terminal solutions are preferred when sensor cables need to be concentrated in a specific marshalling cabinet.
  • Speed ​​Monitoring: Real-time monitoring of shaft speed, supporting full-range coverage from low-speed turning gear operation to extremely high-speed operation.
  • Overspeed Protection: Provides extremely fast response time (typically less than 30 milliseconds), triggering a stop command via relay output.
  • Keyphasor Signal Distribution: Processes acquired speed pulses into keyphasor signals and shares them with vibration, displacement, and other modules via the backplane for synchronous equipment analysis.
  • Reverse Rotation Monitoring: Detects unexpected reverse rotation of the shaft and triggers an alarm.
Description
The Bently Nevada 133434-01 I/O Module with external terminations is designed for use with the 3500/50M tachometer module, offering dual-channel input for signals from proximity probes or magnetic pickups. Unlike the 133442-01 internal termination version, 133434-01 connects to an external terminal block via a dedicated cable, making it ideal for installations where field wiring needs flexibility or separation from the module. This design allows operators to manage wiring complexity while maintaining precise speed, rotor acceleration, and rotor direction monitoring.

Each 133434-01 module supplies buffered outputs via Euro-style connectors, which can be used directly by other 3500 monitors or the rack backplane. The module consumes 5.8 Watts and operates reliably in industrial conditions from -30°C to +65°C (-22°F to +150°F). Compared to 133442-01, 133434-01 provides the advantage of flexible external wiring without modifying the internal module design, making it easier to accommodate large or complex sensor installations.

The 3500/50M tachometer system paired with 133434-01 supports configurable monitoring options, including speed monitoring, setpoint alarming, speed band alarms, zero-speed notification, rotor acceleration detection, and reverse rotation alerts. Its peak hold feature records the highest forward speed, highest reverse speed, or the number of reverse rotations, providing critical machine data for diagnostics and maintenance. This capability, combined with external termination flexibility, makes 133434-01 a robust solution for varied industrial environments.

Mounted in a single full-height rear slot, the 133434-01 integrates seamlessly into the 3500 frame and supports redundant configurations as required. Compared with 133442-01, the external termination approach reduces installation constraints in certain field layouts and allows easier reconfiguration of sensor connections while maintaining high signal fidelity. Overall, 133434-01 delivers reliability, flexibility, and precise tachometer monitoring for critical rotating machinery.
